was observed in France in 1871, in Germany 73, in Switzerland, the 

 Netherlands and Italy in 75, in Russia 80, in Sweden 82, in Finland 

 1890, at the same time it also spread in Australia and Africa. Rostrup 

 found it near Nyborg F. Aug. 29. 74 (R 74 c 6. 79 "), and Jeppesen 

 was the first to find it in Jutland viz. near Horsens Septb. 6. 78. To 

 judge by the statements at hand, its attacks have probably been some- 

 what more severe in the beginning than is now the case, Rostrup 

 writes that in a short time the fungus would cause the most splendid 

 Malvaceae to assume a miserable appearance. Rostrup has also on one 

 leaf of Malva silvestris counted about 2000 sori, in each of which 

 were found about 4000 teleutospores, each of which will produce eight 

 basidiospores. 



Althaea officinalis &. rosea common. Lavatera arborescens &. Malva crispa.

 folia not uncommon.

Heter-eu-puccinia, st. I May on the leaves of Adoxa, st. II— III

Schroeter (89) considered this species a Hemipuccinia and Puccinia 

 albescens a Fucciniopsis which opinion Rostrup and most other myco- 

 logists adopted till Bubak (04''^°) by cultivating experiments proved 

 that st. Ill of the latter species is an autonomous species of the type 

 of Micropuccinia and that the cluster-cups are in genetical relation to 

 Puce, argentata. The aecidial mycelium penetrates the host-plant, either 

 the whole plant or single branches, the cluster-cups break forth both 

 on the stems, petioles, leaves and flowers (Liro 08"'). On Adoxa 

 moschatellina there is also found a Aut-eu-puccinia, Puce, albescens 

 (Grev.) Plowr., which seems to be quite rare and not yet found in 

 Denmark.

Micropuccinia, May— June, the mycelium is perennial in the affected 

 plants, producing only teleutospores year after year (see Plowr. 89 ^°'), 

 is often found together with Puce, argentata st. I; not uncommon.
